Abstract

PROBLEM TO BE SOLVED: To solve the problem that an aluminum foil laminated film is split and a liquid and air are leaked from a split portion when being punctured with the needle of a water server since a conventional liquid packing bag supplying a hydrogen-containing beverage liquid to the water server has an outer layer made of the aluminum foil laminated film and an inner layer made of a film.SOLUTION: A liquid packing bag is set in a water server, is inserted with a hollow needle. A hydrogen-containing beverage liquid is flown down from the needle by gravity. The breakage of a punctured portion by the needle is prevented by making an outer layer due to the vacuum packing of a uniaxially stretched multilayer film or a uniaxially stretched monolayer film after an inner bag consisting of a metal foil laminated film and being an inner layer is fully filled with the hydrogen-containing beverage liquid to the mouth of the inner bag and sealed.

Description

本発明は、飲料用の液体を充填する液体用包装に関し、更に詳しくはウオーターサーバーにセットされて気体の水素を含有する飲料用液体を供給するのに好適な液体包装袋、及び該液体包装袋を用いてウオーターサーバーに水素ガス含有飲料用液体を供給する方法に関するものである。   The present invention relates to a liquid packaging for filling a beverage liquid, and more particularly, a liquid packaging bag set on a water server and suitable for supplying a beverage liquid containing gaseous hydrogen, and the liquid packaging bag. The present invention relates to a method of supplying a hydrogen gas-containing beverage liquid to a water server using

最近、水素水が生体内の代表的な活性酸素であるヒドロキシラジカルを還元消去することが分かり、水素ガスが様々な疾患の治療と予防、アンチエイジング、美容、スポーツ時の乳酸生成の抑制等に効果があることが明らかにされつつあり、水素を含有する飲料用液体特に水素水が飲料分野で注目されて来ている。   Recently, hydrogen water has been found to reduce and eliminate hydroxy radicals, which are the typical active oxygen in the body, and hydrogen gas can be used for the treatment and prevention of various diseases, anti-aging, beauty, suppression of lactic acid production during sports, etc. It has been clarified that it has an effect, and hydrogen-containing beverage liquids, particularly hydrogen water, have attracted attention in the beverage field.

一方、ここ十数年来ウオーターサーバーが各企業や一般家庭でかなり広く使用し始められている。これは、水道水に疑問を持ち天然水をボトルで購入していた人々が購入や搬送の手間を省くためにガロンボトルで購入するようになり、このガロンボトルをセットするウオーターサーバーの購入使用が広がっていることによる。特に、近時放射能汚染のおそれからもウオーターサーバーの使用が増えている。   On the other hand, water servers have begun to be used widely in companies and general households for the past ten years. This is because people who had doubts about tap water and purchased natural water in bottles began to purchase in gallon bottles in order to save time and money for purchase and transportation. By spreading. In particular, the use of water servers is increasing due to the recent danger of radioactive contamination.

そこで、この両者を併用して、ウオーターサーバーで水素水を提供する例が特許文献1のように見られつつある。この特許文献1は、ウオーターサーバーのタンク内に人工ゼオライトを設置し、このゼオライトで水素を発生させるものである。また、インターネットにも、ウオーターサーバー内に投入した特殊セラミックで水素を発生させるものが多数開示されている。   Thus, an example in which both are used together and hydrogen water is provided by a water server is being seen as in Patent Document 1. In Patent Document 1, artificial zeolite is installed in a tank of a water server, and hydrogen is generated from the zeolite. The Internet also discloses a number of special ceramics that generate hydrogen using a water server.

ところが、水素分子(水素ガス)は、ウオーターサーバーの水入れを形成するポリカーボネートボトルの基材(バリア層)より分子量が小さく、ボトルから短時間(精々2日〜5日程度)で蒸散してしまう。また、ウオーターサーバーのボトル内の水は消費されるにつれて水面が下がり、水の上の空気層に水素ガスが揮発するため、ボトル内の飲料には殆ど水素ガスは存在しないことになる。   However, hydrogen molecules (hydrogen gas) have a smaller molecular weight than the base material (barrier layer) of the polycarbonate bottle that forms the water reservoir of the water server, and will evaporate from the bottle in a short time (about 2 to 5 days at best). . Further, as the water in the bottle of the water server is consumed, the water surface falls and hydrogen gas volatilizes in the air layer above the water, so that there is almost no hydrogen gas in the beverage in the bottle.

特開2010−188331号公報JP 2010-188331 A

この問題を解決するために、ウオーターサーバーにセットされて中空のニードルが差し込まれ、重力によって飲料用の水素水をニードルから流下させる液体包装袋が提案されている。また、ウオーターサーバー用のポリカーボネートボトルは、使用後回収する手間がかかり、その点でも、ワンウエイ式の液体包装袋が称揚されつつある。   In order to solve this problem, there has been proposed a liquid packaging bag that is set in a water server, into which a hollow needle is inserted, and hydrogen water for drinking flows down from the needle by gravity. Also, polycarbonate bottles for water servers require time and effort to recover after use, and in this respect, one-way type liquid packaging bags are being promoted.

ところで、従来提案されている水素水用の液体包装袋は、内層をフイルム、外層をアルミ箔積層フイルムで構成したものである。液体包装袋は、上部に空間が生じないように口部まで一杯に充填した場合、内部の飲料物が流下するとその分だけ体積が減少するため空気が溜まる空間ができない特徴がある。また、この外層がアルミ箔のウオーターサーバーは、水素ガスを通さないので、飲料物内に含まれる水素ガスはずっと止まっている。   By the way, a conventionally proposed liquid packaging bag for hydrogen water has an inner layer made of a film and an outer layer made of an aluminum foil laminated film. The liquid packaging bag has a feature that, when filled up to the mouth so as not to create a space in the upper part, the volume is reduced by that amount when the beverage inside flows down, so that there is no space for storing air. In addition, since the water server of this outer layer made of aluminum foil does not allow hydrogen gas to pass through, the hydrogen gas contained in the beverage has stopped.

ところが、この外層がアルミ箔積層フイルムの液体包装袋は、ウオーターサーバーにセットし、内部の液体を流下させるニードルを穿刺するとアルミ箔積層フイルムが裂けてしまい、穿刺した部分から水素水や空気が漏れて使い物にならないことが判明した。   However, if this outer layer is an aluminum foil laminated film liquid packaging bag, set in a water server and puncture the needle that allows the liquid inside to flow, the aluminum foil laminated film will tear, and hydrogen water and air will leak from the punctured part. Turned out to be useless.

本発明者は、この問題を解決するために種々研究した結果、本発明を完成させたものである。即ち、本発明は、ウオーターサーバーにセットされて中空のニードルが差し込まれ、重力によって水素含有の飲料物をニードルから流下させるものであって、金属箔積層フイルムを内層とし、一軸延伸多層フイルム(或いは一軸延伸単層フイルム)を外層とし、内層に外層を被せたものを真空包装機に投入して外層を内層に密着させたたことを特徴とする液体包装袋である。或いは、一軸延伸フイルムの裁断片を金属箔積層フイルムの外側の一部に真空包装して密着させるものである。真空包装する場合の真空の度合いは、真空度が高いほどよく、圧力ゲージで−760mmHg〜−740mmHgである(ゲージ圧表記/絶対真空は−760mmHg)。より好ましくは、−760mmHg〜−750mmHgである。   As a result of various studies to solve this problem, the present inventor has completed the present invention. That is, the present invention is set in a water server, a hollow needle is inserted, and a beverage containing hydrogen is allowed to flow down from the needle by gravity. The metal foil laminated film is used as an inner layer, and a uniaxially stretched multilayer film (or The liquid packaging bag is characterized in that a uniaxially stretched monolayer film) is used as an outer layer and the inner layer is covered with the outer layer, and the outer layer is brought into intimate contact with the inner layer. Alternatively, the cut pieces of the uniaxially stretched film are vacuum-packed and adhered to a part of the outer side of the metal foil laminated film. The degree of vacuum in vacuum packaging is better as the degree of vacuum is higher. The pressure gauge is -760 mmHg to -740 mmHg (gauge pressure notation / absolute vacuum is -760 mmHg). More preferably, it is -760 mmHg--750 mmHg.

本発明の液体包装袋は、アルミ箔積層フイルムなどの金属箔積層フイルムを内層とするため、飲用物から水素ガスが発生しても液体包装袋の外に漏出や飛散することがない。また、液体包装袋の上部に空間が生じないように注入口部まで一杯に飲用物を充填するので、内部の飲料物が流下するとその分だけ体積が減少するため空気が溜まる空間ができない。従って、液体包装袋内の飲用物には元の水素ガス濃度が常に保たれる。   Since the liquid packaging bag of the present invention uses a metal foil laminated film such as an aluminum foil laminated film as an inner layer, even if hydrogen gas is generated from a drink, it does not leak out or scatter outside the liquid packaging bag. In addition, since the drink is filled up to the inlet so that no space is created in the upper part of the liquid packaging bag, the volume is reduced by that amount when the drink inside flows down, so there is no space for air to accumulate. Therefore, the original hydrogen gas concentration is always maintained in the drink in the liquid packaging bag.

しかも、本発明の液体包装袋は、ニードルを刺し入れても、外層に保護されて内側層のアルミ箔積層フイルムが破れることが無く、しかも、外側の一軸延伸多層フイルムが刺し入れたニードルをきつく抱え込んで隙間を形作らないため、刺し入れたところから液漏れや空気漏れが生じることがない。従って、液体包装袋内の飲用物を最後までスムーズに排出する事が出来る。   Moreover, the liquid packaging bag of the present invention is protected by the outer layer even if the needle is inserted, and the aluminum foil laminated film of the inner layer is not torn, and the needle pierced by the outer uniaxially stretched multilayer film is tight. Since it does not form a gap, it does not cause liquid leakage or air leakage from where it is inserted. Therefore, the drink in the liquid packaging bag can be smoothly discharged to the end.

アルミニウム箔などの金属箔は、どのような金属箔であっても水素ガスの通過を阻止する能力を持っている。金属箔としては、アルミニウムやアルミニウム合金の箔の他に、チタン、ステンレス、ニッケル、パーマロイ、ベリリウム銅、燐青銅、洋白、モリブデン、真鍮、ニクロム、タンタル、亜鉛、錫、銀ロウ、銀、銅、鉄、鉛、コパール、ジルコニウムなどの各種金属の箔が用いられる。只、実際上は大量に市販されているアルミニウム箔が用いられる。金属箔の厚みは、包装資材としては大体6〜30μm程度のものが用いられるが、実際上は12〜18μm程度である。   A metal foil such as an aluminum foil has the ability to prevent the passage of hydrogen gas, whatever the metal foil. In addition to aluminum and aluminum alloy foils, titanium, stainless steel, nickel, permalloy, beryllium copper, phosphor bronze, white, molybdenum, brass, nichrome, tantalum, zinc, tin, silver solder, silver, copper Various metal foils such as iron, lead, copal and zirconium are used.ア ル ミ ニ ウ ム In practice, aluminum foil that is commercially available in large quantities is used. The thickness of the metal foil is about 6 to 30 μm as a packaging material, but is actually about 12 to 18 μm.

但し、金属箔にはピンホールが付き物であり、12〜18μm程度ではピンホールから水素ガスが蒸散する可能性がある。ピンホールを無しにするには、50μm以上の箔が必要になるとも言われている。しかし、50μm以上ものアルミニウム箔は固くて包装用には向かない。そこで、金属箔を二重にするとピンホールが完全にカバーされるので、水素水中の水素ガスの長期保存が可能となる。ここに、金属箔を二重にするとは、2枚の金属箔の間にフイルムを介在させ、且つ金属箔の両側もフイルムで保護するものである。このようにすると、全体の剛性もそう大きくならず、しかもピンホールがほぼ完全に防止される。   However, a pinhole is attached to the metal foil, and hydrogen gas may evaporate from the pinhole at about 12 to 18 μm. It is said that a foil of 50 μm or more is required to eliminate pinholes. However, aluminum foil of 50 μm or more is hard and unsuitable for packaging. Therefore, if the metal foil is doubled, the pinhole is completely covered, so that long-term storage of hydrogen gas in hydrogen water is possible. Here, double metal foil means that a film is interposed between two metal foils and both sides of the metal foil are protected by the film. In this way, the overall rigidity is not so great, and pinholes are almost completely prevented.

金属箔積層フイルムとしては、ポリエチレンテレフタレ−ト(PET)/金属箔/ポリエチレンなどの多層ラミネート、ナイロン/金属箔/ポリエチレン(又はポリプロビレン)、PET/金属箔/高密度ポリエチレンなどが使用される。後者でアルミニウム箔のものはレトルト食品の包装に賞用されている。これら各種フイルムの厚みは8〜30μm程度のものが用いられる。尚、フイルムと金属箔の張り合わせはドライラミネートが主であるが、溶融押出しやカレンダー法などでも行うことができる。   As the metal foil laminated film, a multilayer laminate such as polyethylene terephthalate (PET) / metal foil / polyethylene, nylon / metal foil / polyethylene (or polypropylene), PET / metal foil / high density polyethylene, etc. are used. The latter, aluminum foil, is used for packaging retort foods. These various films have a thickness of about 8 to 30 μm. The lamination of the film and the metal foil is mainly dry lamination, but can also be performed by melt extrusion or calendering.

一方、一軸延伸(無延伸)多層フイルムとしては、ポリエチレンやポリプロピレン、ナイロン等の一軸延伸多層フイルムが用いられる。これらのフイルムの貼り合わせもドライラミネートが主であるが、溶融押出しやカレンダー法などでも行うことができる。厚みは25μm〜50μmである。或いは、ポリエチレンやポリプロピレン、ナイロン等の一軸延伸(無延伸)単層フイルム単独でも用いることができる。   On the other hand, as the uniaxially stretched (non-stretched) multilayer film, a uniaxially stretched multilayer film such as polyethylene, polypropylene, or nylon is used. The lamination of these films is mainly dry lamination, but can also be carried out by melt extrusion or calendering. The thickness is 25 μm to 50 μm. Alternatively, a uniaxially stretched (non-stretched) single layer film such as polyethylene, polypropylene, or nylon can be used alone.

液体包装袋の形状としては、5リットルや15リットル入りの米袋状のものや、バケツ状や円筒状或いは立方体状のものなどが考えられる。米袋状のものは、背張りと上下部のシールをすることにより、或いは三方袋(シートを折り曲げて残りの三方をシールする)や四方袋(2枚のシートの四方をシールする)で形成することができる。バケツ状や円筒状或いは立体状のものは、スタンディングタイプのもので、例えば、シートを折り曲げて底部を複雑に形成するとともに両側部をシールして形成するなどにより得られる。尚、水素ガスを含有する液体としては、水や鉱泉水以外に、ジュースや牛乳、アルコール類等が用いられる。   As the shape of the liquid packaging bag, a rice bag shape containing 5 liters or 15 liters, a bucket shape, a cylindrical shape or a cubic shape may be considered. A rice bag-like product is formed by sealing the back and upper and lower parts, or by using a three-sided bag (folding the sheet to seal the remaining three sides) or a four-sided bag (sealing the four sides of the two sheets). be able to. The bucket shape, cylindrical shape, or three-dimensional shape is a standing type, and can be obtained, for example, by bending a sheet to form a complicated bottom portion and sealing both sides. In addition, as liquid containing hydrogen gas, juice, milk, alcohols, etc. are used other than water and mineral spring water.

本発明の効果は以上説明した通り、内側層がアルミ箔積層フイルムで外側に一軸延伸(無延伸)多層フイルム(或いは一軸延伸フイルム単層)を真空包装した液体包装袋であるところから、飲用物に含有されている水素ガスが抜け出ることもなく、飲用物を流下させるニードルを刺し入れても内側層のアルミ箔積層フイルムは決して破れない。しかも、外側の一軸延伸多層フイルム(或いは一軸延伸フイルム単層)がニードルをしっかり把持し、穿刺箇所から水や水素ガスがもれることもない。   As described above, the effect of the present invention is a liquid packaging bag in which an inner layer is an aluminum foil laminated film and a uniaxially stretched (non-stretched) multilayer film (or a uniaxially stretched film single layer) is vacuum packaged on the outside. The inside of the aluminum foil laminated film is never broken even if the needle for letting the beverage flow down is inserted. Moreover, the outer uniaxially stretched multilayer film (or uniaxially stretched film single layer) firmly holds the needle, and water and hydrogen gas do not leak from the puncture site.

ニードルで穿刺しても液漏れや水素ガス漏れが生じない液体包装袋を簡単な構造で製造できた。   A liquid packaging bag that does not cause liquid leakage or hydrogen gas leakage even when punctured with a needle could be manufactured with a simple structure.

図2は、本発明の液体包装袋の元となるアルミ箔積層フイルム1で背貼り2し底部3aをシールした袋地3である。この袋地3は、図1(a)のアルミ箔積層フイルム1を厚み50μmの一軸延伸ポリエチレンフイルム1Pを内側にして背張りしたものである。図1(a)中、符号1Aは厚み13μmのアルミ箔、1Nは厚み30μmの一軸延伸ナイロンフイルムである。袋地3は、この他三方シールや四方シールにより得ることもできる。   FIG. 2 shows a bag 3 in which the back 3 is sealed with an aluminum foil laminated film 1 which is the base of the liquid packaging bag of the present invention and the bottom 3a is sealed. This bag 3 is formed by backing the aluminum foil laminated film 1 of FIG. 1 (a) with the uniaxially stretched polyethylene film 1P having a thickness of 50 μm inside. In FIG. 1A, reference numeral 1A denotes an aluminum foil having a thickness of 13 μm, and 1N denotes a uniaxially stretched nylon film having a thickness of 30 μm. The bag 3 can also be obtained by a three-way seal or a four-way seal.

この袋地3から得られる液体包装袋は米袋状のものであるが、液体包装袋としては、その他立方体状のものや円筒状のものなど種々考えられる。また、寸法も使用するウオーターサーバーの形状に合わせて決定する。液体包装袋の容量も、使用するウオーターサーバーの形状に合わせて5〜15リットル程度の範囲で決定する。   The liquid packaging bag obtained from the bag 3 is in the shape of a rice bag, but various other liquid packaging bags such as a cubic shape and a cylindrical shape are conceivable. Also, the dimensions are determined according to the shape of the water server to be used. The capacity of the liquid packaging bag is also determined in the range of about 5 to 15 liters according to the shape of the water server to be used.

次に、この袋地3を図2に示すように、立てて水素含有飲料用液体Wを充填してから、上辺3bを加圧接着して、図3に示すような液体入り袋容器4とする。この際、袋容器4の内部上部に空隙(dead volume)が無いように口元一杯まで充填する。   Next, as shown in FIG. 2, the bag 3 is erected and filled with the hydrogen-containing beverage liquid W, and then the upper side 3b is pressure-bonded. To do. At this time, the bag container 4 is filled to the full mouth so that there is no dead volume in the upper part inside the bag container 4.

この液体入り袋容器4に、一軸延伸多層フイルムの袋5を被せてから真空包装機に投入して真空にすると、アルミ箔積層フイルム1の表面に一軸延伸多層フイルム5が密着した本発明の液体包装袋6(図4)が得られる。一軸延伸多層フイルムの代わりに一軸延伸の単層フイルムを用いてもよい。尚、図1(b)中符号5Pは厚み30μmの一軸延伸のポリエチレンフイルム、5Nは厚み30μmの一軸延伸のナイロンフイルムである。真空包装する場合の真空の度合いは、真空度が高いほどよく、圧力ゲージで−760mmHg〜−740mmHgである(ゲージ圧表記/絶対真空は−760mmHg)。より好ましくは、−760mmHg〜−750mmHgである。   When the bag 5 of uniaxially stretched multilayer film is put on the bag 4 containing the liquid and then put into a vacuum packaging machine and evacuated, the liquid of the present invention in which the uniaxially stretched multilayer film 5 is in close contact with the surface of the aluminum foil laminated film 1. A packaging bag 6 (FIG. 4) is obtained. A uniaxially stretched monolayer film may be used instead of the uniaxially stretched multilayer film. In FIG. 1B, reference numeral 5P denotes a uniaxially stretched polyethylene film having a thickness of 30 μm, and 5N denotes a uniaxially stretched nylon film having a thickness of 30 μm. The degree of vacuum in vacuum packaging is better as the degree of vacuum is higher, and is −760 mmHg to −740 mmHg with a pressure gauge (gauge pressure notation / absolute vacuum is −760 mmHg). More preferably, it is -760 mmHg--750 mmHg.

水素水を充填するアルミ箔積層フイルムの表面に、一軸延伸多層フイルム(或いは単層フイルム)の裁断片5aをヒートシールし、四方目をシールする際に真空包装する。若しくは、真空チャンバーの中で四辺を同時にシールする。この場合、全体を覆う一軸延伸多層フイルムの外層袋は不要になる。図5〜図8は、この例を示すものである。この袋地7は、図2の袋地3の一方の面のほぼ中央部に、一軸延伸多層フイルム(或いは一軸延伸単層フイルム、無延伸単層フイルム)の裁断片5aを載置し、その四方5bを充填作業の事前にヒートシール(或いは真空包装)して袋地3と一体化したものである(図5)。この袋地7に、図6のように水素含有飲料用液体Wを充填した後図7のように上辺3bを加圧接着して、液体入り袋容器8とする。この際、袋容器8の内部上部に空隙(dead volume)が無いように口元一杯まで充填する。   The uniaxially stretched multilayer film (or single layer film) cut 5a is heat-sealed on the surface of the aluminum foil laminated film filled with hydrogen water, and vacuum-packaging is performed when the fourth side is sealed. Alternatively, the four sides are sealed simultaneously in a vacuum chamber. In this case, the outer layer bag of the uniaxially stretched multilayer film covering the whole is unnecessary. 5 to 8 show this example. In this bag 7, a cut piece 5 a of a uniaxially stretched multilayer film (or a uniaxially stretched single layer film or an unstretched single layer film) is placed at substantially the center of one surface of the bag 3 of FIG. The four sides 5b are heat-sealed (or vacuum packaged) in advance of the filling operation and integrated with the bag 3 (FIG. 5). After filling the bag 7 with the hydrogen-containing beverage liquid W as shown in FIG. 6, the upper side 3b is pressure-bonded as shown in FIG. At this time, the bag container 8 is filled up to the mouth so that there is no dead volume in the upper part inside the bag container 8.

すると、図8に示すような液体包装袋9が得られる。この液体包装袋9は、一軸延伸多層フイルムが液体包装袋全体ではなく、その一部に設けられている点が液体包装袋6と異なり、他は液体包装袋6と同じである。   Then, the liquid packaging bag 9 as shown in FIG. 8 is obtained. This liquid packaging bag 9 is the same as the liquid packaging bag 6 except that the uniaxially stretched multilayer film is provided not on the entire liquid packaging bag but on a part thereof.

得られた液体包装袋6(或いは液体包装袋9、以下液体包装袋6で説明する)は、例えば図9に示すウオーターサーバー10のボトルホルダー11にセットされる。そうすると、ボトルホルダー11の底部に設けられたニードル12が液体包装袋6の底を穿孔し、飲料液貯留タンク13と連通するニードル12の中空の導液管12aから水素ガス含有液体Wが流下する。飲料液貯留タンク13に溜まった水素ガス含有液体Wは、ニードル12の下端に接する位置で落下停止する。   The obtained liquid packaging bag 6 (or liquid packaging bag 9, which will be described below as liquid packaging bag 6) is set, for example, in a bottle holder 11 of a water server 10 shown in FIG. Then, the needle 12 provided at the bottom of the bottle holder 11 perforates the bottom of the liquid packaging bag 6, and the hydrogen gas-containing liquid W flows down from the hollow liquid conduit 12 a of the needle 12 communicating with the beverage storage tank 13. . The hydrogen gas-containing liquid W accumulated in the beverage liquid storage tank 13 stops dropping at a position in contact with the lower end of the needle 12.

飲料液貯留タンク13の水素ガス含有飲料用液体Wは導管14で下方に送られ、途中電子冷却装置15とヒーター16を通り、冷水供給口17、温水供給口18を介して下のコップ19、20に冷水21或いは温水22を供給する。尚、水素ガス含有飲料用液体Wは温度が上昇すると水素ガスが蒸散しやすくなるが、短時間故そう問題はない。或いは、冷水のみ供給するようにしてもよい。符号23はウオーターサーバー10の台、24は床である。   The hydrogen gas-containing beverage liquid W in the beverage storage tank 13 is sent downward through the conduit 14, passes through the electronic cooling device 15 and the heater 16, and passes through the cold water supply port 17 and the hot water supply port 18, and the lower cup 19. Cold water 21 or hot water 22 is supplied to 20. The hydrogen gas-containing beverage liquid W tends to evaporate as the temperature rises, but there is no such problem because it takes a short time. Alternatively, only cold water may be supplied. Reference numeral 23 is a stand of the water server 10, and 24 is a floor.

液体包装袋6の中の水素ガス含有飲料用液体Wは、自重により飲料液貯留タンク13から流下する。その折り、液体包装袋6は真空を保ったまま空気圧に押されて変形していく。   The hydrogen gas-containing beverage liquid W in the liquid packaging bag 6 flows down from the beverage storage tank 13 by its own weight. As a result, the liquid packaging bag 6 is deformed by being pushed by air pressure while maintaining a vacuum.

尚、液体包装袋6の底を穿孔したニードル12は、図10に示すようにアルミ箔積層フイルム1及び一軸延伸フイルム5を突き破るが一軸延伸フイルム5がアルミ箔積層フイルム1を保護するため孔は開くが破れず、しかも一軸延伸多層フイルム(或いは単層フイルム)5がニードル12にまとわりつき、水素ガス含有液体W及び空気の漏れを完全に封止する。また、アルミ箔積層フイルム1も、一軸延伸フイルム5が真空包装されているため決して裂けることがなくニードル12をしっかり保持する。   Note that the needle 12 having the perforated bottom of the liquid packaging bag 6 breaks through the aluminum foil laminated film 1 and the uniaxially stretched film 5 as shown in FIG. 10, but the uniaxially stretched film 5 protects the aluminum foil laminated film 1 so that the holes are not formed. The uniaxially stretched multi-layer film (or single-layer film) 5 clings to the needle 12 and completely seals the leakage of the hydrogen gas-containing liquid W and air. Further, the aluminum foil laminated film 1 also holds the needle 12 firmly without tearing because the uniaxially stretched film 5 is vacuum packaged.
